I'm looking for the idle timeout setting that controls after how long a connection is closed when the HTTP Keep-Alive option is enabled in a Route via HTTP assertion. Is there a system property that we can change for this and if so, what is it or where can we see what the default idle timeout is?
Otherwise, what controls how long connections are kept opened when the keep-alive option is checked?
Would this be it?

Yes, that setting will control how long connections are held open by the gateway for HTTP Routing assertion. We recommend setting this to be 5s which should become the default in newer versions.
